Patent 10490902 was granted and assigned to Acer on November, 2019 by the United States Patent and Trademark Office.
A mobile device includes a metal mechanism element, a ground plane, a feeding element, a parasitic element, and a dielectric substrate. The metal mechanism element has a slot. The ground plane is coupled to the metal mechanism element. The feeding element is coupled to a signal source. The feeding element extends across the slot. The parasitic element is coupled to the ground plane. The parasitic element extends across the slot. The ground plane, the feeding element, and the parasitic element are disposed on the dielectric substrate. An antenna structure is formed by the feeding element, the parasitic element, and the slot of the metal mechanism element.
